In a laboratory environment, it is cost prohibitive to run automotive battery aging experiments across a wide range of possible ambient environment, drive cycle, and charging scenarios. Because worst-case scenarios drive the conservative sizing of electric-drive vehicle batteries, it is useful to understand how and why those scenarios arise and what design or control actions might be taken to m...

Research on regenerative brake technology of electric vehicles based on a direct-drive

In this paper an analysis is done on the main drive of rolling mill which consumes about 60 to 70 % of total energy of the plant. The existing rolling mill in India are using the 3 phase induction motor and flywheel to drive the rolling mill. The electric motor transmits the power to flywheel with the help of V-belt. An attempt has made after analysis of existing mill that by using some soft st...

The stability control of two separate electric vehicle (EV) motors by using only single five-leg inverter (FLI) is the motivation of this study. This paper proposes an electric differential (ED) in a FLI to serve dual separate induction motor (IM) drive-based wheels of an EV traction drive system. FLI is developed to replace the two normal three-phase voltage source inverters that need to indep...

Traditional loaders with engines present the drawbacks of high energy consumption and poor emissions performance. The usage an electric motor instead engine in loader can effectively improve efficiency emissions. is mainly used earthwork construction unstructured roads. Compared to automobile, during working process loader, load fluctuates violently, vibration serious. A large torque range oper...

This paper shows a model of five-phase synchronous motor with permanent magnets and simulation control device. A in the SimInTech software product is built. The transient time 0.03 s when stepped input applied. When load moment inertia increases by factor 10, accuracy speed response decreases. maximum error 40% at 0.2 s. consequence changing object. It suggested to perform identification adapt ...
